Abstract
Due to its low-cost and simplicity, flyback converter is used to generate high-voltage in color TVs. In addition, using flyback converter has the advantage of driving Horizontal-Yoke with the same circuit. In this paper operation of this converter in TV sets is analyzed. Some analytical formulas are derived and confirmed by simulation and experimental measurements. Regulation of high-voltage is examined and its dependence on component values is derived. Finally a method to calculate component values for best regulation of high-voltage is proposed.
